HORACE H. MORGAN, OF KILLBUOK, NEW YORK FROST-PROTECTOR FOR FOUNDATIONS.

SPECIFICATION forming part of Letters Patent No. 385,2'78, dated June 26, 1888.

Application filed November 1 2, 1887. Serial No. 254093. (No model.)

To al whom it may cocerm Beitknown that I, HORACE H. MoRGAN, a citizen of the United States, anda resident of Killbuck, in the County of Cattaraugus and State of New York, haveinvented certain new and useful Improvements in Frost-Protectors for Foundations; and Ido declare thefollowing to beafu1l,clear, and exactdescription of theinvention,such as will enable others skilled in the art to which it appcrtains to make and use the same, reference being had to the acconpanying drawings, and toletters or figures of reference marked the'eon,which form a part of this specification.

Figure l of the drawings is a vertical longitudinal section ofmy improved frost-protector. Fig. 2 is a transverse section.

The invention relates to improvements in devices and the manner ot' protecting walls, abutments, posts, and kind red structurcs from the action of frost.

It is well known that at certain times the frost contained in the gronnd beneath astructure has an Upward or heavng teudency, teuding to the dcstruction or damage of the structure.

The object of my invention is to provide a means of protecting the wall or other structure from the direct action of the frost, which I accomplish by the device hereinafter described, and illustrated in the aecompanying drawings.

In the drawings, A reprcsents a stone or other solid foundation embedded in the earth below the possible frostdepth. Upon this foundation is vertically placed a post or hollow eylinder, B, reaching to or above the ground-surfacc. i

C is aplate or nutofsuitable material placed on the upper end ot' the post B. The plate C may be provided with an internal thread to engage the tapped upper end of the post B, as shown at c,- or the post B may be provided with a circumferential shoulder, c', as shown in the drawings, against which the lower face of the plate C may abut. In the latter case the thread within the plate is not required.

Upon the plate C the superstructure is to be' placed in any manuer best suited to the structure. I

Dis a hollow pipe or sleeve surrounding the post B and sufficiently large to leave -a space between its interier wall and the post B. The pipe D rests upon the foundation A and extends upward to a point near the surface ot' the ground and somewhat below the plate' G. This pipe D is designed to protect the foundationpost from the action of the frost, which it does in the following inanner: When the earth or Water which surrounds the hollow pipe D becomes frozcn, and the work of the frost begins its Operations of heaving, as it is commonly called, which is in fact a steady irresistible force upward, the pipe D, being frozen to the ground, yields to the upward pressure and slides easily upward around the interior post, leaving the post intaet.

The posts and protecting-sleeves may be placed at any distance apart.

Having described my invention,whatIclaim, and desire to secure by Letters Patent, is

l. In a frost-protector, the eombinatiomwith the foundation A and the sliding sleeve D, resting on the foundation A, of the post B, provided with the circumferential shoulder c and the plate pieee designed to fit thereon, substantially as specified.

2. In a frost-protector for foundations, the combinatiouwith the fonndation A, below the frost line, of the post B, having the threaded upper end, the plate C, having the threaded opening to engage the threads of the post, and the sleeve D, resting upon the foundation, substantially as specified.

In testimony wherrof [atfix my signature in presence of two witnesses.

HORACE H. MORGAN.
